Produced mainly by the BBC and Discovery Channel, Nature’s Great Events is a wildlife documentary series that looks at how seasonal changes produced by the sun change the weather and how some of the most amazing wild events happen in response to these changes. Each chapter takes a look at the challenges and opportunities that these changes impose to some specific animal species.
Narrated by David Attenborough in the UK version and by Hasani Issa in the USA version, this series will give us a close view on these events with some of the most stunning photography.
In this fifth episode set in Botswana, the arid plains of the Kalahari are transformed into a wetland by the annual flooding of the Okavango delta. Thousands of animals follow the ancient migration routes across the desert fighting against dehydration and punishing heat. The behavior of elephants among other species will be closely followed as they try to survive.
